Running a node

Hello everyone,

I know there are similar posts on this subject but I haven’t quite found the answers that I am looking for. I have strong conviction about bitcoin and because of that I have become increasingly interested in running a node. If someone has a YouTube video or an article they could reply with that would be great. Otherwise I’m hoping a few of my questions from below can get answered.

I make daily purchases of bitcoin but I only HODL. Will I still be supporting the network by running a node?

What are the privacy advantages to running a node?

What type of node is best for how I use bitcoin?

What type of computer will I need?

Does running a node limit what exchanges I can purchase from? (Currently use River)

Will I have to change how I store my BTC when running a node? (Currently use paper wallets)

I appreciate any information that you can provide!
